Oslob is one of the most popular snorkeling spots in the world, but also one of the most controversial. At this location, whale sharks have been fed by guides and fishermen for 15 years to attract tourists and sell tours. This practice has several harmful consequences on the marine fauna, and we do not recommend supporting the industry. If you still want to go there by yourself, here’s the necessary advice.

How to go snorkeling with whale sharks in Oslob?

The whale shark interaction area is just off Barangay Tan-awan, a small village located about 7 miles/10 kilometers south of Oslob. The experience is regulated and you will need to book a tour through one of the many agencies in the area to get there. It is not allowed to reach the snorkel area by swimming from the shore.

The cost of the whale shark tours is 2000 pesos per person for non-residents (2023 rate). Some companies also offer day tours from Moalboal (where there are very good snorkeling spots, such as Panagsama Beach and White Beach) or Cebu.

Try to come very early, as the site is most of the time crowded. After a briefing on the whale shark interaction guidelines, your guide will take you to the snorkeling area aboard a small boat. Most whale sharks are encountered 50 meters from the beach.

Oslob whale shark watching rules and controversies

Oslob whale shark watching is a very controversial activity because the whale sharks are fed by the guides to prevent them from migrating. In addition to modifying their natural behavior and changing their migratory patterns, sharks suffer from poor nutrition and are exposed to human interactions.

Hundreds of snorkelers and divers visit this spot every day, many of them breaching the guidelines and touching the sharks, as guides do to prevent the sharks from bumping their boats. Collisions with boats are frequent, and many sharks show signs of infection and lesions.

If you still decide to visit this spot, you will snorkel in a 15 to 22 feet/5 to 7-meter-deep area. Underwater visibility is usually great, particularly in the morning when the site is still not totally chaotic.

Oslob features an impressive density of whale sharks, with dozens of individuals gathering here in a very small area.

Observation guidelines impose keeping a distance of 9 feet/3 meters from the sharks, but these often approach much closer to the boats and snorkelers, as they are fed between the outrigger and the hull of the boats. The whale shark is the biggest fish in the sea and can measure up to 32 to 40 feet/10 to 12 meters in length, and is truly impressive.
